Species abundance correlations carry limited information about microbial network interactions

The effect of a perturbation on correlation-based network inference.
(A) Example of a timeseries. Dashed lines represent sampling timepoints. Sampling was performed during the perturbation (t1 = green, t2 = yellow, t3 = blue and t4 = grey) and at equilibrium (t5 = dark blue). Alternatively, sampling was performed randomly between t = 100 and t = 1000 (random = pink). (B) Results (F1-scores) of network inference for sampling at various timepoints. After a perturbation all species grow back to their original equilibrium. The bars of the boxplots indicate the variability outside the middle 50% (i.e., the lower 25% of scores and the upper 25% of scores). Dashed lines represent median results of sampling during equilibrium.
